Starting with a rough sketch of a "manazipper", which I envision attacking magic points. I want it to "zip" around the screen, a hard to hit monster with normal attacks, but extremely vulnerable to flare dart and lightning. A 40-50+ monster that may drop tiny mana potions when destroyed. I think it would fit into a forest map not created yet that has something to do with magic. Current concern is the size...should I aim for a smaller sketch or is its size appropriate for a faster than character movement?

Here goes a more detailed body facing full left. I changed the eye to orange w/out detail, which could leave it open to becoming more buglike. I did not add a pointed nose nor wings to make sure the shape is better.

@ the eyes...Perhaps you could off white the eyes? I wouldn't go Grey though more to the super light Yellow... Also I think bugs need BIG eyes, like you had them before you recolored them.. makes them more bug like.
